I also experimented with customization on this before doing it for reals on my Urban Filofax. The silver curlicues are my doing, as well.
It's pretty cute and comes with nice, undated, weekly (two-pages-per-week) and monthly (two-pages-per-month) filler pages, in addition to some note paper and and address book with tabs. The lines in the monthly are not too narrow and light enough that they can be ignored. Key quality, for me!
This organizer does accept FF refills, but the FF refills are slightly smaller in height and width. The pages in the PlanAhead are 3x5.
The photo, below, shows the inside but I don't think it shows all the tabs that came with it (not 1000% sure). I cannibalized parts of it when I was testing out how to live with my more recent Filofax purchase. Once I decided I could live small, and with rings, I decided to buy the FF so I could incorporate a wallet into the set-up and thus always have my planner with me.
It also has two vertical slits, one on the left of the open cover, and one on the right of the open cover. You can also see the small, horizontal pocket on the left of the open cover.
It's made by PlanAhead. I was able to find the website before, but I can't find it now! Sorry! However, it didn't say much, other than telling you where you could buy the products. I recall a listing of CVS, Walgreen's, and Walmart. Maybe more, but I'm not sure so I won't hazard a guess. I saw them at CVS and Walgreen's.
Here's a link to a pretty cool, faux-leather one, which will have a more broad appeal than sky-blue denim! I haven't seen this one before, I like it.
All in all, other than missing a billfold and change pocket, this is a great value and very competitive with the Filofax. I'm really surprised the company isn't putting more effort into marketing them and making them available online as they are a solid product.
